12 Claims.

This invention relates in general to a container from each otherparticle. A maximum covering effect may thus be obtained from a minimumof material; in addition, the powder may be blown into ordinarilyinaccessible places.

It is an object of this invention to provide a power sprayer which isadapted to eject powder in the form of a fine cloud.

It is a further object of this invention to provide a powder box andpowder sprayer in combination, whereby a powder may be stored and thenejected, when used, in the form of a fine cloud.

It is another object of the invention to provide a powder box andsprayer which is adapted to contain a powder in a sealed conditionbefore use and is adapted to eject the powder in the form of a finecloud when used.

Further objects of the invention as well as its construction, use andoperation will in part be obvious and will in part be set forth in thefollowing disclosure.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand, accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth,

In the accompanying drawings forming a material part of this disclosure:

Fig. 6 is a side cross section of the article, similar to the view inFig. 3, showing a further form of the invention.

Fig. 7 is an exploded side elevation, partially in section, showing anozzle and puncturing needle according to a still further form of the-invention.

Fig. 8 is a fragmentary enlarged detailed view of the backing member.

' Fig. 9 is a fragmentary sectional view similar to Fig. 3, showing amodified form of the invention.

Referring to the figures in detail, there is shown a powder box,generally designated l0, comprising in general a box II and a sprayingnozzle l2. The box H has flexible side walls, and preferably is somewhatpointed, with the nozzle substantially at the apex of the point andslightly above the cross sectional center line of the box.

Referring to Figs. 2- and 3, there is shown the structural detail of thebox ill. The box is roughly triangular in shape, having rounded corners,and

having a relatively curved top l4 and bottom IS.

The edges of the box iii are curved, and adjacent thereto are smallfolds or creases i1. Both the 5 curved edges and the creases areflexible, whereby flexibility is imparted to the entire box structure.Thus, the top and bottom of the box may be squeezed substantiallytogether without interference from the edges.

Mounted within the box, and preferably toward the center thereof is aspring l8, comprising a bent strip of spring steel or the like, andhaving a thickened portion 19 toward the front end of the box. As shownin the figure, the spring (refer also to Fig. 5) is bent to provide anupper leaf 2.0 and a lower leaf 2| substantially parallel with the topand bottom of the box, and having a curved section l9 joining the leavesspringably together. The open end of the upper leaf is bent down to meetthe lower leaf, whereby there is imparted to the spring a fineresiliency.

Mounted in the front end of the box, substantially at the apex of thetriangular shape of the box is a spraying nozzle 22. A neck 23, near thebase 24 0f the nozzle is adapted to fit into the box and to be retainedtherein, leaving the base inside the box and the mouth or body 25 of thenozzle 22 protruding from the box I l. The base 24, being wider than theneck 23, securely anchors the nozzle in position in the box.

A backing member 26 (see also Fig. 8) is mounted within the box bearingagainst the base 24 of the nozzle, and serves partially to retain thenozzle in its position, and to prevent the nozzle from being forcedwithin the box. This backing member 26 is a metal strip,

bent at the ends forming flanges 26 to fit the inner contour of the box,and to extend slightly back from the front end of the box along the topand bottom of the box. Slightly above the center of the backing member26 is a thin indented section 21 which is adapted to receive the base ofthe nozzle 22. At least this central section 2'? is constructed of a sot, puncturable material, such as, for example, a soft metal.

The backing member is fitted within the front of the box, adjacent tothe nozzle, and optionally is secured there by means of the snug fitbetween the backing member 26 and the box ll alternatively, added meanssuch as, for example, rivets, screws, glue or the like (means not shownin the drawings) secure the backing member firmly to the box.

According to another form of the invention (refer to Figs. 2, 3 and 4)the backing member comprises a fiat metallic ring 26; roughly triangularin shape to fit around the inside of the edge of the box II. This formof the ring, likewise has an indented section to receive the base 24 ofthe nozzle 22, the indented section being thinand puncturable, as in thecase of the backing member shown in Fig. 8.

In the use of the article shown in the drawings, the box is partiallyfilled with The powder is then sprayed, by rapidly forcing together thetop and bottom of the box. Be-

and therefore the gust 'of air starting from the rear of the box passesthrough the nozzle, carryoughly dispersed in the. air, thereby utilizingit insures that the air will pass for a relatively long distance overthe surface of the powder, so that the surface will be thoroughlystirred up. Similarly, the location of the nozzle slightly above thecenter of the box insures that the powder will not cover the nozzle, sothat it is certain that the powder will be carried out in a gust of air,not merely forced through the nozzle by the pressure behind it.Accordingly. every provision is made to cause thorough dispersion of thefine powder particles.

When one puii of powder-air mixture is expelled from the box, thecompressing pressure on the box is released, and the spring expandsdrawing'ln another puff of air. This new air in turn passes to the rearof the box, powder, so that the next succeeding expulsion of air willhave an even more thorough dispersion of again stirring up the powderwas somewhat caked in gular shape, wherein the front angle is less thanwhich is shown in the figures and is the preferred form of theinvention, permits the box to be inserted in a corner even where a shortnozzle is used to prevent the nozzle from being broken off. Likewise,this construction is highly satisfactory for ejecting powder into thesmallest cracks and crevices.

It is also to be noted that the construction of the present invention issuch that it may not be refilled at any time with a substitute or with apowder of inferior quality.

In Fig. 6 there is shown a different arrangement of parts within the boxH. In this form of the invention, the nozzle 22 is similarly mountedwithin the front of the box, by means of a backing member 26. The sidesof the box are flexible. as in the preceding figures. Toward the frontof the box, and inside the box is mounted a relatively heavy spring 18,and toward the rear of the box is a lighter spring 18 each 'urging thetop M and the bottom I5 of the box apart. In this form of the invention,the easy compressibility of the rear of the box is emphasized. In thiscase, not only is the air carried from the rear of the box, butadditionally the backing member 26 is protected from damage because thefront section of the box is compressed only slightly, and accordinglyonly a slight bending of this backing member takes place. Similarly,there is practically no tendency to cause the nozzle 22 to becomeseparated from the box by means of bending of the front portion.

In Fig. 7 is shown a nozzle and puncturing means which is adapted to beused in any of the forms of the invention. In this form, the inside ofthe nozzle 22 is at least partially threaded, to receive a pin 28 whichalso is at least partially threaded. A wide or wing handle 29 on the pinserves at a gripping means. In use, the pin is initially loosely.screwed into the nozzle'with the point 30 of the pin either free fromthe back ing member 26 of the box, or at most only barely touching thebacking member. To open the box, this pin is screwed into the nozzleuntil the backing member is punctured. The pin is then removed, and thepowder sprayed outas desired. To reclose the box, the pin is once againscrewed into the nozzle, effectively closing the opening.

In Fig. 9 there is shown means for adjusting the compressibility of thebox, and in particular of the front and rear sections of the box. Inthis form of the invention the spring i8 is siidably mounted within thebox I l, and its position therewithin is controlled by means of knobs 29projecting slightly outside the box through a slot 30 in the bottom l5of the box. When the spring is slid forward, the rear of the box is moreeasily compressed, and when slid back, the rear is more difiicultlycompressed. I Thus there is provided a compressibility controlv on thebox.

It is to be understood that various features of the box have beenpresented sep ely. b h some or all of these features may be combinedwith one another. For example, the slidable While I have illustrated anddescribed the preferred embodiments of my invention, it is to beunderstood that I do not limit myself to the precise constructionsherein disclosed and the right is reserved to all changes andmodifications com ing within the scope of the invention as defined inthe appended claims.
